G a

Definition

relation between gravitational force and viscous force in fluid films flowing over walls, expressed by

$G a = g l^{3} / v^{2}$ ; where

$g$ :: is acceleration of free fall (ISO 80000-3: Space and time),

$l$ :: is characteristic length (ISO 80000-3: Space and time), and

$v$ :: is kinematic viscosity (ISO 80000-4: Mechanics) of the fluid

relation entre la force de gravitation et la force visqueuse dans des films fluides s'écoulant sur des parois, exprimée par:

$G a = g l^{3} / v^{2}$ ; où

$g$ :: est l'accélération due à la pesanteur (ISO 80000-3: Space and time);

$l$ :: est la longueur caractéristique (ISO 80000-3: Space and time); et

$v$ :: est la viscosité cinématique (ISO 80000-4: Mechanics) du fluide

Notes

The Galilei number is also given by

$G a = R e^{2} \cdot R i$ or +

$G a = R e^{2} / F r^{2}$ ; where

$R e$ :: is the Reynolds number (Reynolds number),

$R i$ :: is the Richardson number (Richardson number), and

$F r$ :: is the Froude number (Froude number).

Le nombre de Galilée est également donné par:

$G a = R e^{2} \cdot R i$ ou

$G a = R e^{2} / F r^{2}$ ; où

$R e$ :: est le nombre de Reynolds (Reynolds number);

$R i$ :: est le nombre de Richardson (Richardson number); et

$F r$ :: est le nombre de Froude (Froude number).
